From the IUCN Red List Species Account:

 

Range Description

This species is known from Sumatra, Siberut, Borneo (where it has been recorded from many scattered localities), the Philippines, Peninsular Malaysia and India (Arunachal Pradesh State). Records from northern monsoon areas (Thailand, Viet Nam) are probably referable to Rhacophorus verrucosus and Rhacophorus bisacculus (Inger et al., 1999). In the Philippines, it is known from a few mountain localities on Luzon, Leyte, Polillo, Negros, Bohol, Mindanao and Basilan. It probably occurs more widely than current records suggest, especially in areas between known sites.

Habitat and Ecology

It is an arboreal species of tropical forest and shrubland. Breeding choruses have been observed at lower elevations in swampy areas and small quiet mountain streams. The tadpoles develop in puddles or small pools of stagnant water.

Population

It is only occasionally encountered, but it can then be found in substantial numbers (Dring 1979). In Borneo, rather large breeding choruses have been observed at a number of sites; hence it appears to be abundant. It is uncommon in Sumatra and Siberut in Indonesia. In the Philippines there have been very few records of this species and it is still known from less than five localities.

Population Trend

Decreasing

Major Threats

Deforestation of lowland areas is the major threat to this species.

Conservation Actions

Clarification of the taxonomy of the R. appendiculatus complex is required before meaningful conservation measures can be implemented. In the Philippines, the remaining tracts of intact lowland and montane rainforest on the islands where this species occurs should be designated as protected areas. In Borneo, several well-protected parks in Sabah and Sarawak provide refuges for this species, and elsewhere in its range it also occurs in protected areas. Effective preservation of lowland forests in Kalimantan is essential.

Taxonomic Notes

A detailed study of the geographic variation of the various populations of this species, from India to Indonesia, is warranted. The Greater Sunda islands, Peninsular Malaysia and the Philippines support variable populations that require further study because they inhabit different microhabitats and are subject to different threats.
